Abstract

High-Efficiency gear Transmission of the present invention relates to the field of gear transmission technique, particularly to a high-efficiency double internal gear planetary transmission with small tooth number difference. High-Efficiency Gear Transmission of this invention provides with an entirely new double-ring gear and extra short toothed gears with changed gear parameters in order to obtain high transmission efficiency with reduced power loss in bearings and gear engagement. High-Efficiency Gear Transmission according to the invention comprises at least one double-ring gear composed of two integrated coaxial gear rings. Said double-ring gear having different tooth numbers on each ring is mounted on an eccentric shaft through planetary bearings. The double-ring gear performs planetary movement with two fixed-axle gears respectively. The vertical projections of the tooth widths of the two gear rings of said double-ring gear on their common axis at least partially coincide with each other. Both said gear rings are composed of either outer or inner gears. The distance between the projections of the center lines of their tooth widths in the direction of their common axis is zero. The distance b between the internal surface of the outer gear ring of said double-ring gear and the external surface of the fixed-axle gear engaged with the inner gear ring of said double ring gear must be not less than twice the eccentric distance a of the eccentric shaft. If the double ring gear and the fixed-axle gears engaged with it are all helical gears, the two internal helical gears are of the same hand, and so are the two external helical gears. The high-efficiency gear transmission is provided with an extra short toothed gear pair with changed gear parameters. Its addendum coefficient ha is less than 0.5, the absolute value of its modified coefficient difference X is not more than 0.1, preferably equal to zero, and the modified coefficients of both extra toothed gears are preferably equal to zero. The two internal helical gears are of the same hand and so are the two external helical gears while said extra short toothed gear pairs are used for the two internal gear pairs of the double internal gear planetary transmission.
